MySQL Abstraction Class

This is a class that I've used in some of my projects for years. It's a simple wrapper to MySQL written in PHP5 that allows you to connect, run queries and get results. It's been used in production sites for some time now and I've re-factored it several times.

Setup

Add a composer.json file to your project:

{
  "require": {
      "rcastera/mysql-wrapper": "v1.0.0"
  }
}

Then provided you have composer installed, you can run the following command:

$ composer.phar install

That will fetch the library and its dependencies inside your vendor folder. Then you can add the following to your .php files in order to use the library (if you don't already have one).

require 'vendor/autoload.php';

Then you need to use the relevant class, and instantiate the class. For example:

Getting Started

require 'vendor/autoload.php';

use rcastera\Database\Mysql\Mysql;

$db = new Mysql('localhost', 'DATABASE', 'USERNAME', 'PASSWORD');

Examples

Select all records from contacts table.

<?php
    require 'vendor/autoload.php';
    use rcastera\Database\Mysql\Mysql;
    $db = new Mysql('localhost', 'DATABASE', 'USERNAME', 'PASSWORD');
?>
<?php $contacts = $db->executeQuery('SELECT * FROM contacts')->asObject(); ?>
<?php if ($contacts): ?>
<ul>
    <?php foreach($contacts as $contact): ?>
    <li><?php echo $contact->first_name; ?> <?php echo $contact->last_name; ?></li>
    <?php endforeach; ?>
</ul>
<?php else: ?>
<p>No contacts found.</p>
<?php endif; ?>
<?php unset($db); ?>

Insert a record into the contacts table.

<?php
    require 'vendor/autoload.php';
    use rcastera\Database\Mysql\Mysql;
    $db = new Mysql('localhost', 'DATABASE', 'USERNAME', 'PASSWORD');
?>
<?php $inserted = $db->executeQuery('INSERT INTO contacts (first_name, last_name, email) VALUES ("Isabella", "Castera", "email@domain.com")')->wasInserted(); ?>
    <?php if ($inserted): ?>
    <p>Contact Isabella inserted with id, <?php echo $inserted; ?></p>
    <?php else: ?>
    <p>No contacts found.</p>
    <?php endif; ?>
<?php unset($db); ?>

Delete a record from the contacts table.

<?php
    require 'vendor/autoload.php';
    use rcastera\Database\Mysql\Mysql;
    $db = new Mysql('localhost', 'DATABASE', 'USERNAME', 'PASSWORD');
?>
<?php $deleted = $db->executeQuery('DELETE FROM contacts WHERE first_name = "Isabella"')->wasDeleted(); ?>
    <?php if ($deleted): ?>
    <p>Contact Isabella deleted.</p>
    <?php else: ?>
    <p>No contacts found.</p>
    <?php endif; ?>
<?php unset($db); ?>

Update a record in the contacts table.

<?php
    require 'vendor/autoload.php';
    use rcastera\Database\Mysql\Mysql;
    $db = new Mysql('localhost', 'DATABASE', 'USERNAME', 'PASSWORD');
?>
<?php $updated = $db->executeQuery('UPDATE contacts SET last_name = "Branson" WHERE first_name = "Richard"')->wasUpdated(); ?>
    <?php if ($updated): ?>
    <p>Contact Richard updated.</p>
    <?php else: ?>
    <p>No contacts found.</p>
    <?php endif; ?>
<?php unset($db); ?>
